    Hi, so I’m sure this has been answered before but no matter how much I look I can’t seem to find a solution. I’ve got a jdm 92 1g-gte, it has a new walbro 255 and 12v mod done. But it won’t start, it cranks though. Tested power to pump and when the fp spot in the diagnostics is jumped with the...

    For those who have kept thier fuel filter in the rear, please show your mounting setup. I bought a Fuel Lab Fuel filter off Driftmotion (large size) and I don't believe I can get away with mounting it where the stock one goes. I like the idea of putting it on the other side of the frame rail as...

    Hey guys, This is my first post and good to be a part of the community! I have a '95 GTE swapped 5 speed. Recently I have been having a problem with the fuel pressure. When I turn the key the fuel pressure jumps up to 40psi fuel pump primes and then the fuel cuts off about 2 seconds in and car...

    Tried searching the forums and found no useful answer. The only thread that had an answer, was wrong (Stant Part No: 10817 , CST Part No: 6817 are wrong) or didn't fit my Supra. Does anybody have the size / thread pitch or even better a part number for any 2-WAY VENTED gas caps?

    Hey fellas, I just finished installing the following: AFPR Walbro 450 550cc Injectors LEX AFM 12V Fuel Pump Rewire I installed the AFPR first and noted the stock FP for the 7M. I then dropped the tank and threw in a Walbro 450 and did the 12V rewire. I ran it like this for some time and...

    Hey guys, ran bad gas through my car so had to change my fuel filter, rebuilt my diff while I was at it. On the drive home today a Mk4 supra pulled up to me and asked me to race, I did, but once I got to about 5,250 rpms it just sat there and started bogging, I'm guessing my filter strainer is...

    Hey fellas, Currently in the process of installing some fuel upgrades. I have installed a Walbro 450, 550cc LI Injectors, AFPR, LEX AFM and also the 12V Fuel Pump relay/harness/mod (whatever you wanna call it). I know that for this current setup, AN Fuel lines are a little overkill. However, I...

    Hey fellas. I've been having an issue where my car randomly would crank but would not start. I eventually narrowed down the issue to my fuel pump relay as it was not getting power. There are threads from way back to 2004 describing this issue and all of them had no solutions. I just wanted to...

    Looking for bigger fuel injectors for my 7mge supra, there are many on ebay claiming "NO TUNE, MORE TORQUE", I'm stock 7mge right now with an air intake for nothing more than the sound it provides. What size injectors would be best for a bunch more power and torque, not looking to switch to e85...

    okay, so i just finished upgrading to a mhg and arp studs, i put everything back together and i fixed the leaks on the turbo side and when i finished taking the thing back from a test drive it started leaking on the intake side and only remains leaking for a few minutes after the car is off. i...

    Hey guys! I took the fuel sending unit out of my tank and the low fuel resistor wire got caught and ripped off. I'm assuming its nichrome and can't be soldered, so does anyone know of any way I could repair it? The actual reading seems to be a little wonky as well, as it seems to move relatively...
  12. MKIV (1993-1998)
    Can someone please help me with wiring in the Haltech flex fuel sensor on single turbo series 1 2jz-gte non-vvti? I have it installed but have no idea how the wiring works with attaching it to a 5volt sensor. Do I just bridge into any 5volt sensor in the engine bay, harness, or directly into...
  13. MKIII Technical
    Dealing with a lean misfire, and I have done everything aside replacing the TPS and stock fuel injectors. Car is basically bone stock at the moment but if I am going to take the time to take out the fuel rail it would be nice to know if there are any decent 550cc fuel injector brands/part #s...

    Hi everyone, I'm planning on reaching 400whp on my 7M-GTE and thought of getting one 340lph fuel pump (either DW300 or AEM340), 600cc injectors and an FSE Sytec fuel pressure regulator. I also just bought a GReddy T67 turbo. Now the question is: I've searched around the forum but wanted a...

    Hi, I wanted to know what fuel pump setup to go with for a stock 2jzgte motor with hks twins... hoping for 700-750whp on e85. Ill be running AEM Infinity and would like to use a staged pump setup. I've been told to go various ways by different tuners/shops... twin 450's vs 340 + 525/535/540 I...
  16. MKIV (1993-1998)
    So I'm 2jz swapping my 1971 240z and I'm doing the fuel system now, and I'm looking for a good inline fuel pump that will let me run it NA now and medium power later. I'm thinking about the AEM 50-1005 but my biggest fear is that it might be too high pressure for the stock system. I like this...

    Fuel Hanger assembly was bad, changed to a new one but used the old level sender w/ float, since that still worked after installing the new set up, old float is no longer reading, and the part seems to be discontinued for some years now go figure are there any aftermarket replacements? i like...

    Hi all, I have an 88 that is pretty much bone stock. It seems like it’s running rich (aem air/fuel meter) on idle usually around 17-18 and I know it’s not wrong because I can definitely smell the gas it’s throwing in there. Also it doesn’t seem to idle smoothly except when I have the a/c on...
